Symfony2 form and Doctrine2 - update foreign key in assigned entities fails

Question

I have profiles and studies. One person can finish many studies. The form renders correctly. There is a button \"Add new study\" and with jQuery I add another subform based

Answer 1

Your solution did not work for me. In fact I had already set up the relationship and defined the adder, remover, getter and after I saw your solution i added the setter.

However my setter was not called when the form was submitted.

The solution for me was another one.

In the adder method I added a call to set the owner.

public function addStudie($studie)
{
     $studie->setProfile($this);
     $this->studies->add($studie);
}

And to have this adder called when the form is submitted you need to add to the form collection field the by_reference property set to false.

   $builder->add('study', 'collection', array(
                'type' => new StudyType(),
                'allow_add' => true,
                `by_reference` => false,
                'allow_delete' => true
                    )
            )

Here is the documentation:

Similarly, if you're using the CollectionType field where your underlying collection data is an object (like with Doctrine's ArrayCollection), then by_reference must be set to false if you need the adder and remover (e.g. addAuthor() and removeAuthor()) to be called.
